The invention discloses a new medical biological material. The new material is prepared from 80-200 parts of butyl cyanoacrylate, 0.01-0.1 parts of hydroquinone, 5-24 parts of nano-powder of aloe, 20-55 parts of soybean protein powder, 10-44 parts of chitosan and 1-5 parts of acetic acid. The preparation method is that the chitosan solution of 20-40% concentration is first prepared with deionized water and then heated with deionized water of 2-4 times the volume of chitosan solution. When the temperature is 40 - 60 C, add the remaining components, mix and stir evenly, and adjust the solid content to the production requirements, then you can. The new medical biological material of the invention improves its impact resistance by adding aloe nano-powder, and natural plant extracts essence and ingredients to make it easier to degrade; the chitosan component increases the bacteriostatic activity of the product, and the product of the invention has moderate curing speed, high bonding strength, low heat release during bonding, good toughness of bonding film, little irritation to skin, and various traumas and operations. The incision has high strength and fast adhesion, and no scar after curing.

技术介绍
医用胶水是代替缝针用的新兴医用产品,医用胶水的主要成分是a-氰基丙稀酸酯,其在生物体组织的聚合速度最快。医用胶水在创面血液和组织液中阴离子的作用下,能快速聚合固化成膜并与创面镶嵌紧密,可牢固地保持伤口的对合状态,且胶膜可阻止血球、血小板通过,在凝血酶和纤维蛋白原的共同作用下,封闭创面断裂的小血管可以有效止血,同时胶膜将组织和细菌隔离,还具有抗感染和保护创面的作用。聚合物中的醚链还具有止痛作用,因此医用胶水具有粘和、止血、止痛、消炎、护创、促进愈合等综合功效。与传统的缝合法相比,医用胶水具有以下优点:1、快速止血,粘和过程没有痛苦,不需要麻醉。2、伤口呈线性愈合,无缝针缝线等异物对皮肤的刺激,减少炎症的发生,形成的瘢痕很小,具有良好的美容效果。3、不用拆线,大大缩短就医时间,节省就医费用。4、在腹股沟疝平片无张力修补术中应用化学性医用胶黏合固定补片和创面止血的效果良好,不增加术后复发率,可节省手术时间和减轻术后疼痛,还可减少术后慢性疼痛和局部血肿的发生。现有的医用胶水存在:抗 ...
